Often hardly mentioned and probably the smallest building blocks in size in IoT infrastructures, sensors and microelectromechanical systems (MEMS) have undergone substantial developments in the past decade, addressing and augmenting developments in IoT. Miniaturization, producing at economies of scale, sensor fusion, and the integration of sensors and actuators are some of the key developments.

This Research Note traces the importance of sensors, how MEMS are playing a critical role in IoT, and where the next developments are happening in this field.
